Aim: to improve treatment results of colorectal cancer, complicated carcinomatosis of abdominal cavity, by associated using of endolymphatic chemotherapy (ELCT) and local extremely high frequency (EHF) therapy. Igroup 21 people (33.3%) performed colostomy, then neoadjuvant systemic chemotherapy by the scheme FOLFOX4. It was held two cycles, after two cycles their were received cytoreductive surgery; II group 26 people (41,3%) received cytoreductive operations with early postoperative intraabdominal chemotherapy by oxaliplatin (200 mg/m(2) at day 1 and 5FU 650 mg/m(2) from days 1 to 4. III group 16 people (25,4%) also performed colostomy, then used 2 courses of ELCT with local EHF therapy and all patients were received cytoreductive operations. ELCT was carried out injecting oxaliplatin100 mg/m(2) a day during 12 hours and then 5 FU in doze of 600 mg/m2 a day during 72 hours by the instrumentality of the dozer and LV200 mg/m(2) (2h intravenous infusion). During ELCT patients received local EHF therapy in abdominal cavity for an hour. After chemotherapy the partial regress of tumor observed in 1st group in 4,8 % and in 3rd 37,5 %, stabilization of process noted in 28,6 and 50% cases, progressing 66,7 and 12,5% cases correspondingly to groups. Histomorphologic study of malignant foci after ELCT+EHF therapy showed reduction of specific area of parenchyma cancer cell from 57 till 39% simultaneous growth of stroma from 40 till 58% and in necrosis area from 1,8 till 2,5%. Mitotic activity of tumor cells in the 1st group decreased (average in 22 un.), but in 3rd group it decreased until 11 units. Analysis of life span showed that in 1st group of patients 2year survival rate was 66,7%. In 2nd group of patients 2year survival rate was 42,3%. ELCH+EHFtherapy has high clinic efficacy and promotes to decrease terms of progression of tumor process, increases life span from 0 till 24% and quality of life of the patients. ELCH+EHFtherapy brings to reduction of specific area of parenchyma in cancer cells from 57 till 39% with simultaneous growth of stroma area from 40 till 58% and necrosis area from 1,8 till 2,5%. ELCT+EHFtherapy lowers mitotic activity of tumor cells, activates apoptosis, hemodynamic and metabolic rates., Akbarov E.T., Navruzov S.N., Abdujapparov S.B., Islamov H.D., and Literatura
Radioterapie a chirurgická léčba jsou základní léčebné modality užívané u pacientů se spinocelulárním karcinomem hlavy a krku. Definitivní a pooperační radiochemoterapie je dnes standardní součástí léčebných algoritmů u pacientů s lokoregionálně pokročilým onemocněním. Metaanalýzy randomizovaných studií prokázaly, že radiochemoterapie prodlužuje přežití ve srovnání s radioterapií samotnou. Tohoto benefitu je dosaženo především zlepšením lokoregionální kontroly; dopad na vzdálené metastázy je pouze marginální. Nejčastěji užívaným radiosenzibilizátorem v radiochemoterapii je cisplatina. I přes benefit radiochemoterapie, léčba přináší zvýšené riziko těžké lokální a systémové toxicity. Mezi nové látky, které mohou zlepšit klinické výsledky léčby, patří protilátky proti EGFR. V randomizované studii vedla anti-EGFR léčba s radioterapií k prodloužení přežití oproti radioterapii samotné. V paliativní léčbě jsou monochemoterapie, polychemoterapie nebo kombinace chemoterapie a protilátek proti EGFR vhodnými nástroji ke zpomalení nádorové progrese., Radiation therapy and surgery are the basic modalities of treatment in patients with squamous cell carcinoma of the head and neck. Definitive and postoperative radiochemotherapy is now a standard component of a therapeutic algorithm in patients with locoregionally advanced disease. Several meta-analyses have shown that radiochemotherapy prolongs survival compared with radiotherapy alone. This benefit was mainly due to an improvement in the locoregional control and only had a marginal effect on distant metastases. Cisplatin is a potent radiosensitizer, most commonly used for radiochemotherapy. Despite the benefits of radiochemotherapy, this treatment also carries risks of severe local and systemic toxicities. Newer developments include EGFR antibodies, which seem able to improve the clinical outcome. Anti-EGFR treatment with radiotherapy in one randomised study improved overall survival when compared with radiotherapy alone. In palliative treatment monochemotherapy, polychemotherapy or combination of chemotherapy and EGFR antibodies are appropriate tools against progression of tumors. therapy, palliative chemotherapy., Miloslav Pála, and Literatura 17
